Tsunami modelling
What are tsunami?
Tsunami are long period waves, most often generated by displacement of the sea floor associated with earthquakes, volcanic eruptions or landslides.
Tsunami can cause devastation to coastal communities with potential for destruction of coastal infrastructure, property and loss of life from the powerful waves and their inundation of land.

What can I do to help prepare?
Consult with your local authorities and civil defence representatives to understand and better prepare for tsunami hazard - and get involved with your local community emergency response planning.
